US Visa Applications Must Be Submitted from Country of Residence or Nationality

Can anyone explain a rational political motivation behind this? I realize "less immigrants" is the hand-wavy explanation, but how does this benefit those in charge?

It aligns with their effort to ruin the economic situation of American universities.

Please refer me to the part of the Constitution that enumerates the responsibility of the US government to preserve the business model of the modern university system?

Unless you are arguing that government actions should not be criticized unless they are in violation of the Constitution, your comment makes no sense in the context of any comment that is an ancestor of it in the comment tree.

Did you response to the wrong comment or get a little mixed up about the shape of the comments tree or what?
